GeneCards Summary for OTUD7B Gene
OTUD7B (OTU Deubiquitinase 7B) is a Protein Coding gene. Among its related pathways are Ovarian tumor domain proteases and Protein ubiquitination. GO annotations related to this gene include cysteine-type peptidase activity and obsolete ubiquitin thiolesterase activity. An important paralog of this gene is OTUD7A.
UniProtKB/Swiss-Prot for OTUD7B Gene
Negative regulator of the non-canonical NF-kappa-B pathway that acts by mediating deubiquitination of TRAF3, an inhibitor of the NF-kappa-B pathway, thereby acting as a negative regulator of B-cell responses. In response to non-canonical NF-kappa-B stimuli, deubiquitinates Lys-48-linked polyubiquitin chains of TRAF3, preventing TRAF3 proteolysis and over-activation of non-canonical NF-kappa-B. Negatively regulates mucosal immunity against infections (By similarity). Deubiquitinates ZAP70, and thereby regulates T cell receptor (TCR) signaling that leads to the activation of NF-kappa-B (PubMed:26903241). Plays a role in T cell homeostasis and is required for normal T cell responses, including production of IFNG and IL2 (By similarity). Mediates deubiquitination of EGFR (PubMed:22179831). Has deubiquitinating activity toward Lys-11, Lys-48 and Lys-63-linked polyubiquitin chains (PubMed:27732584). Has a much higher catalytic rate with Lys-11-linked polyubiquitin chains (in vitro); however the physiological significance of these data are unsure (PubMed:27732584). Hydrolyzes both linear and branched forms of polyubiquitin.
